What exactly is a concrete release agent?
A concrete release agent is actually a material put on the development template just before the concrete is put so that the template will not adhere to the concrete surface right after pouring, isn’t easy to take down the cast or affects the finish of the concrete area. Its main role in the design and the concrete area to create a movie that is going to be separated from the two is also known as an separation agent.
A water-based release agent is definitely an important supplementary in the release agent and can change the water-based release agent circulation and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent can be used in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing mould products are not only so as to let the form release to boost productivity and lengthen the life of the mould use. And can make the item thoroughly clean, size qualified, and decrease the creation of scrap, that is an important supplementary important to forms and goods – Water-based Concrete Release Agent.
Concrete release agent plays an essential role in modern building development; its principal role is always to form a layer of remoteness film between the template and the concrete area so that the template will not adhere to the concrete area to ensure that it is easier to dismantle the cast after putting and to maintain the complete of the concrete covering. Here, we will unveil the kinds, features, use and application of concrete release agent at length.
Sorts of concrete release agent
Concrete release representatives can be divided into numerous kinds in accordance with different category methods, and the typical category techniques are as follows:
- According to the the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release representatives, high-gloss concrete release brokers and and so forth.
Features of Concrete release agent
A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is a type of substance coated on the inner wall of the formwork to play the part of lubricating and isolation to ensure that the concrete may be effortlessly detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low price and and so forth. However, not all kinds of concrete release representatives with a selection of components made of templates are suitable for different materials of the template and different construction circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next qualities:
Good isolation efficiency: concrete release agent can develop a dense separation motion picture between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication performance: concrete release agent has good lubricating overall performance, which can lower the rubbing between the formwork and concrete covering, lower the resistance during pouring and boost the construction effectiveness.
Great anti-adhesion overall performance: concrete release agents can successfully prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking apart the formwork.
Good waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Effortless to use and safe: concrete release agent is easy to use; you only need to apply a layer evenly on the formwork; at the same time, it is safe and environmentally friendly and will not pollute the human body and the environment.
When using a concrete release agent, the following steps should be followed:
Prepare tools: concrete release agent is usually sprayed or brushed for construction. You need to prepare construction tools such as a sprayer or brush.
Choose the right release agent: According to the different environments, choose the right concrete release agent, such as indoor use can choose a water-based concrete release agent, and outdoor use can choose an petroleum-based concrete release agent.
Apply the release agent: Pour the appropriate amount of release agent into the sprayer or container, and then evenly spray or brush on the formwork to ensure that each part is coated in place.
Air drying: After application, wait for a period of time to allow the release agent to dry naturally. Generally, it takes 10-20 minutes, depending on the environment.
Pouring concrete: After the release agent is completely air-dried, the concrete can be poured. During the pouring process, care should be taken to avoid air bubbles or voids between the formwork and the concrete area.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When dismantling the formwork, the connectors at the edge of the formwork should be dismantled first, and then the surface of the formwork should be knocked gently to separate the formwork from the concrete area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking down.
Clean up the template: after dismantling the template, the template should be cleaned up to remove the residual concrete and mould release agent. After cleaning, it can be used for the next time.
Application areas of concrete release agent:
Concrete release agent is widely used in all kinds of construction projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding formwork from bonding with concrete and increasing construction efficiency and quality.
Road construction: in road construction, the concrete release agent can be used to isolate the bond layer between the road formwork and concrete surface, to avoid road bubbles, hollow drums and other problems.
Bridge project: In a bridge project, a concrete release agent can be used to isolate the bond layer between the bridge formwork and the concrete area and improve the construction quality of the bridge pier and abutment.
Tunnelling project: In the tunnelling project, a concrete release agent can be used to isolate the bond layer between tunnel formwork and shotcrete surface to improve the quality and safety of tunnel construction.
Nuclear power project: In nuclear power project, a concrete release agent can be used to isolate the bond layer between the shell of nuclear power equipment and internal components to ensure the safety and stability of the equipment.
Other fields: concrete release representatives can also be widely used in water conservancy projects, wharf projects, airport projects and other fields to provide effective formwork isolation protection measures for various building projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the development of the construction industry.
